This study investigates how gene loss affects bacterial fitness in E. coli by analyzing proteomic data and identifying gene categories with varying fitness impacts.

This study identifies putrescine as a signaling metabolite that regulates the transition from nodulation to nitrogen fixation in Rhizobium phaseoli through the dual action of PuuR.

The paper shows that most transcription factors regulate genes involved in multiple biological processes, challenging the one TF/one process assumption.
